“Miss Ayla Lynch had gotten into an argument with her boyfriend at which point, unfortunately, she took out her anger and aggression towards her little 15-month old daughter,” Perry said.

Lynch’s daughter, Brooklyne Mann, died in April, but Perry said completed toxicology report helped lead to an arrest this week.

“At that point we brought the mother in for questioning,” Perry explained. “After several days of questioning her and other people that (were) at the residence, she finally broke down and admitted what she had done to her daughter.”

Perry says Lynch was under the influence of Lortab and methamphetamine at the time of the crime.
